Contact Corrosion

WARNING: This page is about a different car, the 2023 Volkswagen Arteon. However, it is still accessible from the selected car via links, so may be relevant.

Contact corrosion can occur if incorrect fasteners (bolts, nuts, washers, etc.) are used. For this reason, only fasteners with a special surface coating may be installed.
Original parts and original accessories are recommended which were developed and checked for the respective intended purpose.
